Yes, you can define the stock icon's to use in a gtkrc file, define your
theme :

style "skin_icons"
{
  stock["bigknob"] = {{"knob3.png"}}
  stock["smallknob"] = {{"smallknob3.png"}}
  stock["eqslider"] = {{"eqslider.png"}}
}

class "GxKnob" style "skin_icons"
class "GxEQSlider" style "skin_icons"

the knob have the used icon size (witch is free) then.
You could easy change them during runtime.
also all other widgets in this library are them-able with a gtkrc style
file.
for example

style "fastmeter"
{
  GxFastMeter::clr-bottom = "#003808"
  GxFastMeter::clr-middle = "#00ff00"
  GxFastMeter::clr-top = "#ff0000"
  GxFastMeter::over = "#ff0000"
}

style "selector"
{
  fg[NORMAL] = { 0.32, 0.8, 0.16 }
  GtkRange::trough-border = 2
  GtkRange::stepper-size = 8
  GtkRange::stepper-spacing = 2
  GxRegler::value-border = { 2, 0, 0, 0 }
  font_name = "sans 7.5"
  xthickness = 10
  ythickness = 1
}

class "GxFastMeter" style:highest "fastmeter"
class "GxSelector" style:highest "selector"
